    Hypothesis driven compound design and synthesis

INTRODUCTION

BioAscent’s medicinal chemistry CRO services are provided by our highly talented team of chemists, who have extensive experience of prosecuting successful drug discovery programmes gained within leading pharmaceutical and biotechnology companies. We understand the importance of making the right compound, not any compound, and that delivering a successful molecule with the appropriate biological, ADME and safety profile is set at the design stage.

Working in close partnership with you to understand your approach and project needs we can design and synthesise the optimal ligands for your project at all phases of the discovery process (Hit generation, Hit to Lead, Lead Optimisation). We assess and interpret the information from testing and rapidly incorporate it into the next design cycle thereby ensuring rapid progress. With our wealth of knowledge as drug hunters we can quickly and efficiently take your programme to success.

Our synthetic chemistry capabilities include multi-step synthesis of complex molecules, asymmetric synthesis, route design, building block synthesis, parallel synthesis of ligand arrays and reference molecules. 

The synthetic chemistry team is supported by a range of in-house analytical techniques to ensure the quality of the output both for bespoke synthetic chemistry and for the compound library.  These include: 400MHz NMR with multi-nuclei probe and variable temperature capability, LCMS analysis including UPLC, supercritical fluid chromatography to provide access to chiral analysis and preparative enantiomer separations.

MEDICINAL CHEMISTRY CASE STUDY

Working in collaboration with partners at the German Cancer Research Center within the European Lead Factory project (ELF), BioAscent scientists helped discover potent and selective inhibitors of enzymes associated with the development of some cancers and neurodegenerative diseases.  This work has been published in ChemMedChem.

“More importantly, the scientists who were involved in the hit development stage, were fully committed to the success of the project, bringing their own ideas and solutions, which made my role as project owner very comfortable. I would be very happy to work with them again.”

Dr Aubry Miller, Cancer Drug Discovery/Wirkstoffforschung Group Leader, German Cancer Research Center (DKFZ)
